Abstract: A toilet bowl stabilizer base of a plurality of interlocking plates nest together for compression between the bottom of the new toilet bowl and the supporting floor. The plates are congruent and of the same dimensions and have opposing planar surfaces with a circular opening for receipt of the mounting flange and passage of waste. Each base plate has a pair of alignment pegs and cooperating recesses on the opposing side of the plate to interlock the plates together.

Abstract: A leak repair device composed of an elastomeric seal having an outer toroidal portion radially of a central axis and a continuous membrane portion integral with and peripherally enclosed by the toroidal portion. The elastomeric seal is held by a semi-rigid flexible cover member which has a plurality of parallel slots extending across the surface of the cover member. As the cover member is compressed radially against a rigid pipe, the slots permit the cover member to bend to the contour of the pipe. The toroidal portion of the elastomeric seal is compressed against the pipe to seal the leak and the membrane portion encapsulates the leak region to further seal the escape of fluid through the leak repair device.

Abstract: An access panel assembly with a door and multi-functional frame which prevents sagging and warping of the door from the frame, and which is more safely and easily installed in both new and existing building structures. Flush mounting of the door to either face of the frame is achieved by a symmetrical mechanism wherein the inner edge of all four sides of the frame opening contains a molded, shallow groove which is equidistantly located from the two faces of the frame. The door contains on its underside a plurality of molded tabs, wherein each edge of the door has one or more tabs located adjacent thereto. The molded tabs are resilient so that they deflect when the door is press-fitted into the frame from either face. The molded tabs slide into the shallow grooves and hold the door firmly in place. Further, the door also contains one or more knockouts on the underside thereof, wherein each knockout is positioned near an edge of the door.
